JTEC Single Pole MCB Circuit Breaker 10kA
JTEC miniature circuit breakers (MCB) are rated to 60Vdc and are ideal for use in low voltage dc battery, solar and wind energy systems. These devices offer a neat & convenient solution for over-current or short circuit protection, as well as for circuit isolation.

Single pole MCBs are often used for DC loads such as 12/24 volt DC lighting. They are designed to mount onto DIN rail, ideally in a 'distribution' box. We don't recommend MCBs under 6A as they have a higher resistance.

Trip Curve: C
1-way DIN rail mounting.
60Vdc Maximum Voltage.
10kA Breaking Capacity.
Cable sizes up to 25mm2 without using blade terminals.

JTEC Double Pole MCB Circuit Breaker 10kA
JTEC miniature circuit breakers (MCB) are rated to 60Vdc and are ideal for use in low voltage dc battery, solar and wind energy systems. These devices offer a neat & convenient solution for over-current or short circuit protection, as well as for circuit isolation.

Double pole MCBs are often used for lower voltage solar pv arrays and smaller battery banks. They are designed to mount onto DIN rail, ideally in a 'distribution' box. We don't recommend MCBs under 6A as they have a higher resistance.

If being used on a battery bank, check the short-circuit potential of your battery bank is under 10kA - this is generally battery banks of under approx 1000Ah.

Trip Curve: C
2-way DIN rail mounting.
60Vdc Maximum Voltage.
10kA Breaking Capacity.
Cable sizes up to 25mm2 without using blade terminals.

GTEC High Current Double Pole MCB Circuit Breaker
Gtec High Current DC miniature circuit breakers (MCB) are rated from 80A to 125A, and up to 60VDC, making them suitable for use in off-grid solar and wind energy systems. These devices offer a neat & convenient solution for over-current or short circuit protection, as well as for circuit isolation.

Double pole high current MCBs are often used between the solar pv controller and battery bank in smaller off-grid power systems, where the controller current is too high for most standard MCBs, and the battery voltage is 12V or 24VDC (48V battery banks not recommended). These MCBs can also be used for smaller inverters. They are designed to mount onto DIN rail, ideally in a 'distribution' box.

If being used on a battery bank, check the total short-circuit potential of your battery bank is under 6kA - this is generally battery banks of under approx 600Ah.

Trip Curve: C
3-way DIN rail mounting.
60Vdc Maximum Voltage.
6kA Breaking Capacity.
Cable sizes up to 35mm2 without blade terminals.
