JVM3(ISOMAX) Series Moulded Case Circuit Breaker
JVM3 series moulded case circuit breaker, it's applicable circuit of AC 50Hz(or 60Hz), rated insulation voltage 690V(JVM3-125 500V), rated operating voltage AC 690 or below, rated operating current 12.5-800A,for distribute energy of electric and infrequent making and breaking circuitin normal condition. The circuit-breakers are provided with the function of the protection againstoverload and short circuit and under-voltage. The circuit breakers comply with standard of IEC60947-2. The circuit breakers are douple insulating(lnm=400Aor above),the control circuit of the accessories is set apart with the main circuit, and doesn't need to open the cover of the circuit-bresker when install the accessories.
The main contact of the low-voltage circuit breaker is manually operated or electrically closed. After the main contact is closed, the free trip mechanism locks the main contact in the closing position. The coil of the overcurrent release and the thermal element of the thermal release are connected in series with the main circuit, and the coil of the undervoltage release is connected in parallel with the power supply.
When the circuit is short-circuited or severely overloaded, the armature of the overcurrent release pulls in, causing the free tripping mechanism to operate, and the main contact disconnects the main circuit.
When the circuit is overloaded, the thermal element of the thermal trip unit generates heat to bend the bimetallic strip, pushing the free trip mechanism to act, and the main contact disconnects the main circuit.
When the circuit is under-voltage, the armature of the under-voltage release is released, which also causes the free trip mechanism to act, and the main contact disconnects the main circuit.
When the shunt release button is pressed, the armature of the shunt release is pulled in, causing the free trip mechanism to act, and the main contact disconnects the main circuit
