ABB S203P-D1 3-pole miniature circuit breaker with 1 A rated current, D curve tripping characteristic and 25 kA breaking capacity for professional circuit protection.
£75.32
The ABB S203P-D1 is a high-performance 3-pole miniature circuit breaker (MCB) from the ABB System pro M compact S200P series. Designed for dependable overload and short-circuit protection, it is suitable for residential, commercial and industrial electrical installations where high breaking capacity and reliable circuit protection are required.
The S200P range uses ABB's current-limiting technology with two tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short-circuit protection. Its D curve characteristic makes it suitable for circuits with high inrush currents, including transformers, motors, solenoids and other inductive loads.
With a 1 A rated current, 3-pole configuration and 25 kA breaking capacity, the S203P-D1 provides robust protection for low-current three-phase circuits in demanding applications. Its compact DIN rail format supports efficient installation in distribution boards, control panels and automation enclosures.
Miniature circuit breakers protect electrical circuits by automatically disconnecting the supply when overloads or short circuits occur. The ABB S203P-D1 combines thermal and magnetic tripping performance to help protect cables, equipment and connected loads from electrical faults.
The D curve characteristic is designed for circuits where high temporary inrush currents are expected during start-up. This makes the S203P-D1 well suited to transformer supplies, motor circuits, industrial control systems and other inductive load applications.
