The ASK disconnect or fuse terminal blocks 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 terminal blocks will hold 5 x 20 mm or 5 x 25 mm fuses. The ASK-4S or ASK-4LD fuse terminal blocks will hold a 1¼ x ¼' fuse. They're available for 24 Vdc or 110 Vac. The 'LD' models come with an LED blown fuse indicator. The ASK-3A terminal blocks are useful for analog circuits such as 4 to 20 mA signals, the circuit can be opened the input or output currents can easily be read with a multimeter.

The terminal block plastic housing is made from polyamide 6.6 thermoplastic resin with a UL 94 V2 rating for 105°C. This assures ample dielectric strength for any industrial application. The screws and clamps are made of steel with zinc plating, and together they generate a high locking action and provides an excellent vibration and corrosion resistant connection.
