Eaton xPole PXL Miniature Circuit Breaker, 3-Pole, 50A, Type C, 400V AC, 48V DC, 10kA Breaking Capacity 236431 PXL-C50/3

Eaton 236431 PXL-C50/3 is a high-performance miniature circuit breaker from the xPole PXL series, purpose-built for industrial and commercial electrical installations. Featuring three poles and a 50A current rating, this MCB offers robust protection against overloads and short circuits, making it suitable for distribution panels and branch circuit protection in factories, plants, and commercial premises.

The circuit breaker supports both 400V AC and 48V DC voltage systems, providing installers with flexibility to use the same device across a range of applications, including mixed AC/DC environments such as control circuits and backup power setups. Its Type C tripping characteristic is ideal for combined resistive and inductive loads, striking a balance between sensitivity and nuisance immunity.

With a breaking capacity of 10kA, the device delivers maximum safety by rapidly isolating power in case of electrical faults, reducing risk to equipment and personnel. The electromagnetic tripping mechanism assures dependable fault detection, and the instantaneous break time enhances protection during severe overcurrent events.

Installation is streamlined with quick-fit action and DIN rail compatibility, enabling efficient panel assembly or upgrades. The double terminal design facilitates secure wiring of bus bars or cables, and selectable rail arrangement adds further mounting flexibility. The toggle switch actuator ensures straightforward manual resetting and operation.

The xPole PXL-C50/3 is constructed to meet EN 60898 and IEC standards, ensuring quality and global compliance. The IP20 rating provides finger-proof protection and basic resistance to dust ingress, making it suitable for mounting in protected enclosures or switchboards.

Measuring 80mm in width, 52.5mm in height, and 60mm in depth, this compact circuit breaker fits tightly within crowded panels, optimizing available space. Applications include industrial automation panels, commercial distribution switchboards, HVAC installations, and any critical infrastructure requiring reliable circuit protection.

Engineers and facility managers will appreciate the reliability, versatile voltage compatibility, and quick installation features of this Eaton PXL MCB. For more industrial circuit protection products from Eaton, browse the Miniature Circuit Breaker section on EnvMart.
