The ASK disconnect or fuse terminals allow a circuit to be “opened” without disconnecting the wire from the screw connections. These terminal blocks have screw connections for reliable and secure connections. The ASK-2S or ASK-2LD fuse terminals will hold 5 x 20 mm or 5 x 25 mm. The ASK-4S or ASK-4LD fuse terminals will hold a 1¼ x ¼" fuses. They’re available for 24 Vdc or 110 Vac. The “LD” models come with an LED blown fuse indicator. The ASK-3 A terminal is useful for analog circuits such as the 4 to 20 mA signals, the circuit can be opened the input or output currents can easily be read with a multimeter.
