PULS Electronic circuit breakers now offer two new NEC Class 2 variants
PULS has announced the introduction of two new versions of its PISA-M Electronic Circuit Breakers designed specifically for power distribution in NEC Class 2 circuits.
PISA-M enables the safe distribution of load current into four individual Class 2 circuits. This offers a cost-effective alternative to multiple individually approved NEC Class 2 power supplies, reducing acquisition costs, installation time and system approval. If more than four circuits are needed, multiple PISA-M modules can be connected to a power supply.
Two PISA-M variants with NEC Class 2 are available to suit individual system requirements:
· PISA-M-4CL2 automatically adjusts the tripping currents depending on the required voltage. With an output current of 3.75 A per channel at 24 V (max. 92 W) and 4.85 A per channel at 12 V (max. 60 W), the maximum output power always remains within the safe range and just below the specified NEC Class 2 limits.
· PISA-M-402 allows the distribution of a fixed low output current of 2 A per channel at 24 V (max. 48 W) and 12 V (max. 24 W). This module is therefore ideal for sensitive loads with low current requirements, such as sensors.
Both models feature automatic voltage detection, making them flexible and easy to integrate into 12 V or 24 V systems. All features have been integrated into a slim polycarbonate housing with a width of only 22.5 mm, making PISA-M the smallest electronic circuit breaker with four channels on the market. Thanks to its compact design, PISA-M fits into any system.
