ER12-40N6SB

Disconnect switches, also known as switches or breakers, are used to either make or break a circuit. Their most important primary purpose is to disconnect or bypass current flow to facilitate servicing, maintenance or repair. The ER12-40N6SB is a form of disconnect switch component and has a variety of applications and a distinct working principle.

The ER12-40N6SB is a multi-pole, indoor disconnect switch. It is a general-duty disconnect switch, offering a rated current up to 40 Amps, maximum operating voltage of up to 600 Volts, and comes standard with a door-mounted switch operator, push-to-test trip device, and a press-to-lock handle. It is designed for residential and industrial applications where a power disconnect switch is needed.

Applications for the ER12-40N6SB include motor circuit protection, shop wiring, and general-purpose motor branch circuit protection. Additionally, it can be used for lighting protection, recreational vehicle service, construction wiring, and motor maintenance and service. It is also UL listed for use in hazardous locations.

The working principle of the ER12-40N6SB is relatively simple. The switch is designed to open or close a circuit, breaking the path for current flow. This is accomplished by the simple act of rotating the switch handle, which will cause the contacts inside the switch to either move apart or come together, thus either opening or closing the circuit.

At the heart of the ER12-40N6SB are two cylinders containing a series of contact plates. The contact plates are connected to a center shaft which serves to move the contact plates either closer together or further apart. When the switch handle is rotated, a cam inside the switch moves the center shaft, thus pushing the contact plates apart or bringing them together.

In addition to providing power control, the ER12-40N6SB also serves to protect the circuit. The disconnect switch is designed to detect over-current, short-circuit, and overload conditions. When such conditions are detected, the disconnect switch will trip, breaking the circuit and preventing further damage.

In addition to providing power control and circuit protection, the ER12-40N6SB also provides safety to any environment in which it is used. Its robust construction and UL listing ensure that it meets even the most strict safety standards. Additionally, its use in hazardous locations can prevent the risk of electrical shock, fire, and other safety issues.

In conclusion, the ER12-40N6SB is a multi-pole, indoor disconnect switch which has a variety of applications and a distinct working principle. Its robust construction, UL ratings, and ability to detect current overloads make it a great choice for residential and industrial applications.
