LTLK MCBs for Submersible Pumps

Whether your pumping system is large or small, motors are important assets and hence it is crucial to safeguard them. Our LTLK MCBs with K-Curve are designed to protect your pumping system including motors, cables, and starters/controllers from short circuit faults. The functional design also improves the safety of personal during maintenance.

Available in both 2-pole and 3-pole configurations, LTLK MCBs are suitable for 3 phase as well as 1 phase applications.

The trip-free mechanism ensures maximum safety during operation. The motor is always protected even during the accidental case ‘switch on’ at the time of short circuit which is a distinct advantage over fuse. In case of a short circuit fault, there is no need to replace the fuse wire that saves cost and time and hence LTLK MCB has less maintenance and replacement cost.
