CHiNT Miniature Circuit Breaker – 1P+N, C40, 4.5kA

Description

The CHiNT NBH8-40 C40 Miniature Circuit Breaker (MCB) is a high-performance protection device designed for circuits that supply heavy electrical loads. Ideal for residential and commercial electrical panels, this model ensures dependable operation, long-term durability, and compliance with international safety standards.

Featuring a 1P+N configuration, the NBH8-40 provides full protection of the phase conductor and safe disconnection of the neutral line. This enhances safety in distribution systems and helps prevent accidental energizing of the circuit during maintenance.

With a 40A rated current, this breaker is suitable for powering high-demand appliances and equipment such as large air conditioners, pumps, commercial kitchen appliances, heavy-duty outlets, and small machinery. The C-curve tripping characteristic allows it to handle moderate-to-high inrush currents typical of inductive and motor-driven loads.

A 4.5kA breaking capacity provides reliable short-circuit protection for home and light commercial environments. The compact DIN-rail design ensures quick installation, while the ergonomic blue lever enables smooth operation and a clear ON/OFF indication. High-quality terminals ensure secure wiring and excellent long-term conductivity.

Built in accordance with IEC/EN 60898-1, the NBH8-40 series delivers reliable thermal-magnetic protection, ensuring safe and stable electrical performance.
