Описание
PKV(N)tpbe-1 and PKVtpbe-1 heat-shrink sleeves are designed for termination of aluminum or copper conductors of cables with plastic, rubber and polyethylene insulation with armor or shield for voltages up to 1 kV: AVBbShv-1, VBbShv-1, AVVB-1, AVVBG-1, VVB-1, VVBG-1, APvBbShv-1, PvBbShv-1, VVGE, AVVGE, PvVGE, APvVGE, their equivalents and versions. The product's range is developed for 1-, 2-, 3-, 4- and 5-core cables.
Преимущества
- Two types of overcurrent protection: thermal and electromagnetic.
- Independent contact position indicator.
- Can be snapped on to DIN-rail, with double locking.
- Wide operating temperature range from –40 to +50° С.
- Wide lever for convenient switching ON/OFF of the circuit breaker.
- Notches on the terminal clamps reduce the heat loss and increase mechanical strength of the connection.
