Product Features of the 250 Amp MCCB With Enclosure

Constructed for rigorous outdoor new energy applications, this 250 Amp MCCB With Enclosure integrates a highly responsive thermal-magnetic trip unit within a weatherproof, UV-resistant housing.

Integrated Outdoor Protection: Combines a high-capacity circuit breaker with a dedicated IP65 waterproof housing, acting as a complete 250a mccb with enclosure against rain, dust, and direct sunlight.
High-Voltage Capacity: Operates seamlessly at voltages up to 1000V DC, decisively isolating severe faults with a 20kA ultimate short-circuit breaking capacity (Icu).
UV-Resistant Architecture: The rugged PC/ABS blend enclosure is heavily UV-treated to guarantee long-term structural integrity during intense commercial solar exposure.
Reliable Fault Clearance: Utilizes a precise double pole mccb thermal-magnetic trip mechanism paired with an instantaneous 10In tripper to safely interrupt catastrophic overcurrents.
Extended Mechanical Lifecycle: Built for heavy commercial switching, delivering a massive mechanical lifespan of up to 20,000 operations under load.

Commercial Applications for the 250 Amp MCCB With Enclosure

Deploying the EKM6DC-250EL secures vital high-capacity nodes, acting as a highly dependable mccb with enclosure for outdoor utility-scale solar infrastructures.

Applications & Use Cases

PV Combiner Protection: Functions as the primary outdoor protective unit, safely aggregating high-voltage DC strings exposed to harsh environmental elements.
Battery-Side DC Isolation: Secures heavy-duty commercial battery banks directly at the source, managing intense charge and discharge cycles up to 250A outdoors.
Outdoor Energy Storage: Protects massive external energy storage systems from simultaneous electrical overloads and severe environmental degradation.
