Molded Case Circuit Breaker

The compact design of SENTRON VL family of Moulded Case Circuit Breakers (MCCB) coupled with their excellent features make things easier in the world of electrical distribution. Designed with minimum parts and maximum modularity, the new SENTRON VL range of Moulded Case Circuit Breaker (MCCB) offers two choices of trip units  Thermomagnetic trip unit and Microprocessor trip unit. The thermomagnetic (TM) range offers adjustable overload protection and is available from 20A to 630A. The microprocessor (ETU) range in addition to wide band overload protection, offers the option of time selective short circuit protection and is available from 63A to 1600A. The incoming and outgoing side of the circuit breaker can be selected as desired. The SENTRON VL range of circuit breakers conform to the latest standards (IS 13 947 and IEC 60 947) and have been designed to protect cables, motors, transformers, wiring busbars, as well as other plant equipment against thermal overload and short circuits.

High performance : The SENTRON VL range of circuit breakers are rated for operation with no derating upto 50°C ambient. The entire range of SENTRON VL circuit breakers offers service short circuit breaking capacity (Ics) equal to that of the ultimate short circuit breaking capacity (Icu) i.e. Ics = 100% Icu.

Perfectly Modular : Changes are often unavoidable particularly in the final stages of a project. Field installable snap-in internal accessories of SENTRON VL circuit breaker allows easy exchange or retrofit of accessories on site without the need of any special tools.

Operational Safety : The SENTRON VL circuit breakers are suitable for isolation as defined by IS 13 947 & IEC 60 947. Padlocking in the OFF position also guarantees door interlocking feature thereby ensuring complete safety to the operating personnel during maintenance.

Type 2 Co-ordination*: Selection of protection switchgear as per Type 2 Coordination is the most preferred industrial practice for motor protection, as not only it provides a complete protection, but is also economical in the long run.
