✅ CHINT NB1-63H C32 Miniature Circuit Breaker – 2P, 32A, C Curve, 10kA Breaking Capacity
Description (English):
The CHINT NB1-63H C32 is a double-pole miniature circuit breaker (MCB) designed for advanced circuit protection in dual-phase systems. Rated at 32A with a C curve tripping characteristic, this breaker is ideal for moderate-to-high inductive loads such as air conditioning units, power outlets, and light motor applications in residential, commercial, and light industrial settings.
It features a high short-circuit breaking capacity of 10kA at 230V AC, providing dependable protection against overload and short circuit events. The NB1-63H C32 is compliant with EN/IEC 60898-1 and EN/IEC 60947-2 standards for enhanced safety and durability.
Equipped with a toggle-type actuator, the device includes a VisiTrip indicator for quick fault identification and a VisiSafe strip that visually confirms contact disconnection. The compact 36mm width (4-pitch) allows for easy DIN rail installation in modular panel boards.
It offers an insulation voltage rating of 500V and an impulse withstand voltage of 6kV. Operating temperature range spans -35°C to +70°C, with long-lasting performance rated for 20,000 mechanical and 10,000 electrical operations.
