33 KV Panel

Tricolite is a leading 33 KV VCB panel manufacturers & supplier in India. The VCB or Vacuum Circuit Breaker is reliable medium voltage electrical equipment used to prevent the flow of electric current in case of any short circuit. The 33KV indoor VCB panel by Tricolite complies with the requirements of standard IEC 62271-200:2003/IS: 3427:1997.

As a distinguished 33 KV VCB panel supplier, Tricolite’s extensive research & development has led to the creation of high-quality 33KV indoor switchgear and 33 KV panel switchboards. The highest system voltage is rated at 36 KV and operational current at 1250A. The Ingress Protection or IP rating for external compartment in indoor is IP-4X and outdoor is IP-55 while that of internal compartment is IP-2X.

The circuit breaker is designed to deal with the high thermal stress and mechanical stress generated in the insulation and conducting parts due to the flow of the high amount of electric current. Being one of the top 33 KV VCB panel manufacturers in India, Tricolite provides excellent Insulation Level at 70 KV RMS/170 KV Peak.

Tricolite VCB panels are designed to withstand frequent lighting impulse and switching impulse efficiently during its life span. The internal Arc is tested by Tricolite at 31.5KA for 1 sec. The maximum temperature rise is rated at 40°C over Ambient 45°C.
