ETIMAT 10 DC overcurrent circuit breakers are used to protect DC installations. For voltages up to 220 V, a 1-pole switch is used, for higher voltages (up to 440 V) - a 2-pole switch, but with series-connected poles. When connecting ETIMAT 10 DC circuit breakers, pay attention to their polarity. Note: Two 1-pole circuit breakers cannot be used instead of a 2-pole DC circuit breaker.
