FAQs
This MCCB uses a front-terminal connection type designed for compact control panels. It integrates easily with standard busbars and wiring schemes, enabling straightforward installation in space-constrained enclosures while maintaining compliant torque and conductor sizing per the 690 V insulation rating.
The device provides rated service short-circuit capacity (Ics) of 12.5 kA at 240 V and rated ultimate short-circuit capacity (Icu) of 25 kA at 240 V, suitable for protecting feeders and transformers against fault currents. It also supports 415 V AC and 125 V DC operational voltages with a 6 kV impulse withstand.
Yes. With TMF release, 1P configuration, and front-terminal access, this MCCB is well-suited for transformer protection in industrial settings. Its 20 A rated current with high Ics/Icu capacities helps manage fault events, while its compact form factor eases installation in transformer panels and auxiliary switchgear.
The device carries a CE declaration of conformity and RoHS/REACH compliance, along with CMRT and TSCA declarations. It also aligns with IEC standards and WEEE guidelines, supporting global deployments and regulatory traceability in regulated industries.
The MCCB offers high mechanical durability (up to 8500 cycles) and electrical durability (around 1500 cycles), lowering maintenance downtime and replacement costs. Its front-terminal design reduces installation time, while robust short-circuit ratings minimize risk to downstream equipment, delivering favorable total cost of ownership in ongoing operations.
