The Crabtree Loadstar 6MSC Series consists of Type C Miniature Circuit Breakers (MCBs) with a short circuit capability of 6kA, which are meant to protect electrical installations against short circuits and overloads in light industrial, commercial, and domestic uses. The breakers can provide protection for moderate inrush currents and can be installed in inductive load-containing circuits such as transformers and motors.
Type C MCBs in the 6MSC range offer tough performance and are ideal where there is a greater surge current expected. The device is housed in a compact, fire-resistant enclosure with advanced thermal-magnetic tripping technology for accurate fault response and extended service life.
Type C Tripping Curve: Trips between 5 to 10 times the rated current — ideal for circuits with moderate inrush currents.
6kA Breaking Capacity: Safeguards against high fault levels.
Thermal-Magnetic Trip Unit: Provides dual protection against overloads and short circuits.
IS/IEC 60898-1 Certified: Meets global safety and reliability standards.
Compact Modular Design: Saves space in consumer units or panels.
Durable, Fire-Retardant Housing: Ensures safety under harsh conditions.
Clear Status Indicators: Enhances operation and maintenance.
Padlock Provision: Allows secure isolation during servicing.
6MSC06 to 6MSC10: Designed for small inductive loads — ideal for lighting with transformers or fans.
6MSC16 to 6MSC32: Suitable for standard mixed-use circuits including appliances, air handling units, and kitchen equipment.
6MSC40 to 6MSC50: Built for higher current circuits, including submains, motors, and high-capacity equipment with starting surge.
