With secure DIN rail mounting, high short-circuit breaking capacity, and durable construction, this breaker is ideally suited for demanding industrial and commercial environments.
This breaker is designed for DIN rail mounting (DIN-T style), making it ideal for modern loadcentres and distribution panels where space efficiency is critical.
With its durable construction, high short-circuit breaking capacity, and long service life, the DTCB10120D is well-suited for applications in harsh industrial environments.
The NHP DIN-T 1P20A D CURVE Circuit Breaker (DTCB10120D) is a single-phase protective device designed for industrial and commercial electrical systems.
FEATURES:
Provides effective interruption of excessive currents caused by overloads or short circuits to protect connected equipment.
Optimized for high inrush current applications, ensuring that temporary surges (e.g., from motors) do not lead to unwanted tripping while still delivering prompt fault clearance.
Specifically designed for single-phase circuits, offering focused protection for one live conductor.
Engineered for secure, space-efficient installation on standard DIN rails, facilitating easy integration into modern distribution boards.
Capable of safely interrupting high fault currents (typically around 10 kA), ensuring compliance with industry safety standards such as AS/NZS 61009.
