The Schneider Electric GK1EK is a 3-pole fuse-disconnector from the TeSys GK1 range, designed for off-load isolation applications. It features a 50A rated operational current for the power circuit and a 690V AC rated operational voltage. The device is compatible with 14 x 51 mm GG AM type fuses and includes one early-break normally open (NO) contact for signaling.
Designed for convenient installation, the GK1EK supports DIN rail mounting in a vertical position with a tolerance of +/- 23 degrees. It offers screw terminals for power circuit connections, accommodating solid and flexible conductors ranging from 2.5 to 25 mm². The tightening torque for these terminals is specified at 2 N.m.
Environmental specifications include an IP20 degree of protection and an operating temperature range of -50°C to 70°C. The fuse-disconnector meets IEC 60947-3 standards. Its dimensions are 97 mm in height, 88 mm in width, and 89.5 mm in depth, with a net weight of 0.43 kg.
The rated operational voltage is 690 V AC for the power circuit, 500 V AC for the signalling circuit, and 440 V DC for the signalling circuit.
The rated operational current is 50 A for the power circuit and 6 A for the signalling circuit.
The GK1EK fuse-disconnector is compatible with 14 x 51 mm fuses of type GG AM.
The GK1EK fuse-disconnector is designed for DIN rail mounting and can be positioned vertically with a tolerance of +/- 23 degrees.
The operating ambient air temperature range for the GK1EK fuse-disconnector is -50°C to 70°C.
The GK1EK fuse-disconnector has a height of 97 mm, a width of 88 mm, and a depth of 89.5 mm.
