The unique “Double Break” main contact system ensures extremely fast interruption of short circuit currents and substantially reduces main contact wear. The internally symmetrical “Double Break” structure allow reverse power connection. This is the only ACB with this facility in India that only provided by BCH Air Circuit Breaker Manufacturer.

Our Resilient range of MCCB is available in two frame sizes with standard and high performance variants. As the name Resilient implies, the product in this range have been designed and tested to perform excellently in harsh Indian conditions.

This controller provides reversing and plugging operation of slip ring induction motors in heavy duty cranes on trolley services. Upto 5 motor speeds are achievable when used in conjunction with a master controller.

Features

Special Chromium Steel Alloy (AISI406) used for :
a) Higher resistivity (approximately 70% higher than others)Results in overall lighter and compacter unit
b) Low temperature coefficient (approx 72% lower than others) leading tonegligible change in resistance values despite grid temperature variations ( avery important parameter in applications such as crane controls)

Range

Single / Multiple outlet boxes
16/32/63/125A rating
With or without protection
Option of back up protection with :

MCBs
SDFUs
MCCBs

Modular and compact construction
Loop in Loop out facility
Higher degree of ingress protection
7 Tank processed powder coated enclosure
PV gasketing for excellent sealing against dust and water

Advantages

Good starting torque and current performance
Possibility of adjusting starting parameters
No break in supply to the motor during starting
Best suited for cases when either maximum reduction of Inrush current is desired or motor requires longer acceleration time with good starting torque,such as:

Blowers
Pumps
Compressors
Extruders
Crushers

RG-T series are for compensation of balanced loads. RG3-T series are ultimate solution for compensation of unbalanced loads. The compensation is realized by the reactive power of the system through 3 current transformers from 3 phases. This makes RG3-T series a unique solution for unbalanced load compensation .
