Product Details

MCCB Highlights

800V MCCBs for isolator application offer solution for switching various loads such as UPS,battery banks,etc.with many advantages.These MCCBs differ from regular MCCBs only in terms of absence of protection trip units.These MCCBs can be used for following applications for isolation purpose:

·For local isolation:such as very close to motor load

·Incoming of any sub-distribution

·As an isolator for bus coupler

·As an automatic switch

·For switching applications of motors with VFDs,soft starters

lsolator application MCCBs are always backed up by short circuit protection device to protectthe downstream loads/installations against short circuit.Following advantages are offered byisolator MCCBs:

·Suitable for positive isolation

·Available with 3P and 4P versions

·Can be used with under voltage protection

·Remote tripping through shunt release

·Motor operated MCCBs

·Status Feedback possible
