MOLDED CASE CIRCUIT BREAKERS, BUYLOG SECTION 6

— Q-Line bolt-on circuit breakers Special purpose

Q-Line switching neutral circuit breakers - Q-Line switching neutral circuit breakers are designed with an extra pole (neutral) and common trip to de-energize the breaker when it is in the open or tripped state, this allows for enhanced safety and functionality in an electrical system. Some of these applications include but are not limited to generators, renewable energy, and solar applications where back feeding into the grid is possible. - Single-pole circuit breakers take two spaces and two-pole circuit breakers take three pole spaces. - All circuit breakers are built, tested, and listed to UL and cUL standards (UL 489). - Single-pole 15-20A 120/240 Vac circuit breakers are UL listed as SWD (Switching Duty) rated. Suitable for switching 120 Vac fluorescent lighting loads.

Q-Line low magnetic circuit breakers - Q-line low magnetic circuit breakers are designed to protect against short circuits while being more sensitive to overloads. These circuit breakers are suitable for applications with power fluctuations where rapid current spikes may occur or high in rush current is present. - Single-pole 15-20A 120/240Vac circuit breakers are UL listed as SWD (Switching Duty) rated. Suitable for switching 120 Vac fluorescent lighting loads - All circuit breakers are built, tested, and listed to UL and cUL standards (UL 489).
