Larson Electronics EPFDS-110A-3P-3X110A.600V-TD 110A Explosion Proof Fused Disconnect – 600V Rated – Time Delay Fuse – (3) 110A Fuses (2) NPT Hubs

Description:

The Larson Electronics EPFSD-110A-3P-3X110A.600V-TD Explosion Proof Fused Disconnect is designed for use in Class I, II and III environments. Equipped with time-delay fuses, this 3-pole unit contains three 110-amp 600V fuses and two NPT hubs. The explosion proof disconnect offers delayed response to transient surges, making it ideal for addressing pulse currents and temporary overloads associated with motors, HVAC systems and HID lights in flammable work sites.

The EPFSD-110A-3P-3X110A.600V-TD ensures active protection of electrical systems in combustible facilities. Rated at 600V AC, this fused unit contains three 110-amp 3-pole 600V time-delay fuses. The fuses feature 10-second time delay at 500% overload. These explosion proof disconnects are not sensitive to electrical pulses, allowing connected systems to utilize more power without activating the fuse. Time-delay fuses (also known as a short-blow fuse or a slow-blow fuse) can withstand electrical surges for a specific period of time, typically 10-15 seconds. This feature is useful for equipment that relies on high voltage current during startup, such as motors.

Choosing between a time-delay fuse and a fast-acting fuse highly depends on the type of system or device requiring protection, as both protective methods are effective (one is not superior over the other).

The explosion proof disconnect switch/breaker is made of cast aluminum and features a rectangular bolted cover design for uniform and attractive installations. The cover bolts are made from stainless steel. The external on/off lever can be locked into the “off” position with room for up to three padlocks for superior security. The internal circuit breaker handle mechanism is a sliding plate type mounted to the cover. The circuit breaker is trip free of the external handle mechanism.

Hubs: For completing electrical connections, two NPT hubs are provided on the enclosure. One 2″ NPT hub is located at the top of the unit; and one 0.5″ NPT hub can be found at the bottom of the disconnect.

Mounting: Operators can mount the explosion proof disconnect on flat surfaces.

Applications: Motors, VFDs, phase converters, HVAC systems, dryers, fluorescent lights, HID lights, metal halide, high pressure sodium, mercury vapor, petroleum refineries, chemical and petrochemical plants, storage areas, and other processing facilities where hazardous substances are handled or stored.
