Features 30mA sensitivity for enhanced electrical safety, rated at 220V with 6kA breaking capacity. The NL163-2P40A model provides reliable residual current detection without integrated overcurrent protection, making it ideal for supplementary protection in residential and light commercial installations. Complies with standard safety requirements for leakage current protection. Suitable for use alongside separate overcurrent devices in distribution boards and control panels.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"markdown markdown-main-panel tutor-markdown-rendering enable-luminous-fast-follows stronger enable-updated-hr-color\" id=\"model-response-message-contentr_a606c32ac1fcaed5\" aria-live=\"polite\" aria-busy=\"false\" dir=\"ltr\"\u003e\n\u003cp data-path-to-node=\"0\"\u003eThe CHINT NL1-63 Residual Current Circuit Breaker provides vital earth leakage defense for single-phase installations. This 2-pole (1P+N) device features a 40A rated current, a highly sensitive 30mA tripping threshold for direct-contact protection, and a 6kA breaking capacity at 220V\/230V. As a pure RCCB, it operates seamlessly to isolate faulty circuits from ground faults without providing internal overcurrent or short-circuit protection, requiring pairing with an upstream MCB.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"1\"\u003eKey Technical Specifications\u003c\/h3\u003e\n\u003cul data-path-to-node=\"2\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,0,0\"\u003e\u003cb data-path-to-node=\"2,0,0\" data-index-in-node=\"0\"\u003eManufacturer:\u003c\/b\u003e CHINT\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,1,0\"\u003e\u003cb data-path-to-node=\"2,1,0\" data-index-in-node=\"0\"\u003eModel Family:\u003c\/b\u003e NL1-63 Series\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,2,0\"\u003e\u003cb data-path-to-node=\"2,2,0\" data-index-in-node=\"0\"\u003eModel Code:\u003c\/b\u003e NL1-63-2P40A (often referenced sequentially as NL163)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,3,0\"\u003e\u003cb data-path-to-node=\"2,3,0\" data-index-in-node=\"0\"\u003eNumber of Poles:\u003c\/b\u003e 2-Pole (1P + N)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,4,0\"\u003e\u003cb data-path-to-node=\"2,4,0\" data-index-in-node=\"0\"\u003eRated Current (In):\u003c\/b\u003e 40A\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,5,0\"\u003e\u003cb data-path-to-node=\"2,5,0\" data-index-in-node=\"0\"\u003eResidual Tripping Current (IΔn):\u003c\/b\u003e 30mA (High Sensitivity)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,6,0\"\u003e\u003cb data-path-to-node=\"2,6,0\" data-index-in-node=\"0\"\u003eBreaking Capacity:\u003c\/b\u003e 6 kA (6KAIC)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,7,0\"\u003e\u003cb data-path-to-node=\"2,7,0\" data-index-in-node=\"0\"\u003eRated Voltage (Ue):\u003c\/b\u003e 220V \/ 230V AC (50\/60Hz)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,8,0\"\u003e\u003cb data-path-to-node=\"2,8,0\" data-index-in-node=\"0\"\u003eProtection Type:\u003c\/b\u003e Pure Earth Leakage \/ Ground Fault Protection Only\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,9,0\"\u003e\u003cb data-path-to-node=\"2,9,0\" data-index-in-node=\"0\"\u003eMounting Standard:\u003c\/b\u003e 35mm DIN Rail\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-path-to-node=\"3\"\u003eFeature Summary\u003c\/h3\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,0,0\"\u003e\u003cb data-path-to-node=\"4,0,0\" data-index-in-node=\"0\"\u003eDedicated Life Safety:\u003c\/b\u003e Engineered strictly for human and equipment protection against shock hazards, monitoring vector current balances to open the contacts the millisecond an imbalance up to 30mA is recognized.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,1,0\"\u003e\u003cb data-path-to-node=\"4,1,0\" data-index-in-node=\"0\"\u003ePure RCCB Action:\u003c\/b\u003e Operating purely on residual current principles, this unit lacks a thermal-magnetic element for overcurrent protection, meaning it remains entirely dedicated to managing leakage currents safely.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,2,0\"\u003e\u003cb data-path-to-node=\"4,2,0\" data-index-in-node=\"0\"\u003eCompact Din-Rail Form:\u003c\/b\u003e Occupies a standard 2-module width inside standard distribution boards, combining durability and physical indicators for real-time status oversight.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"5\"\u003eThis premium, certified CHINT residual current circuit breaker is fully stocked and available at Electx Electrical Supply to reinforce your low-voltage power distribution setups and custom control panel safety systems.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Chint","offers":[{"title":"Default Title","offer_id":42724326309963,"sku":"NL163-2P40A","price":2200.0,"currency_code":"PHP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0616\/9732\/7179\/files\/CHINT_40A_1P_N_30ma_6KAIC_220V_Residual_Current_Circuit_Breaker_RCCB_NL163-2P40A_without_over_current_protection_Electx_Electrical_Supply.jpg?v=1782539493","url":"https:\/\/www.electxelectricalsupply.com\/products\/chint-40a-1p-n-30ma-6kaic-220v-residual-current-circuit-breaker-rccb-nl163-2p40a-without-over-current-protection","provider":"Electx Electrical Supply","version":"1.0","type":"link"}
