Switch disconnector STV D02 63A 3p 002271004

"Switch disconnector with fuse STV D02 is a device with a replaceable fuse link protecting electrical installations. It allows you to use (similarly to the VL D01 switch disconnector) the operational advantages of the D0 fuse system. Principles of operation of the STV D02 disconnector - In order to replace a burnt-out fuse-link, pull the disconnector's lever down (which will disconnect the circuit), then pull out the drawer and take out the burnt-out fuse-link. After pulling out the drawer with the fuse link, we get a visible insulating break in the circuit. In this way, the disconnector can perform the function of the main protection (for example: pre-meter) and the main circuit breaker.
Advantages:
→ allows you to replace a blown fuse-link without the risk of touching live parts,
→ no need for a fuse head; proper contact of the fuse link is ensured by the appropriate arrangement of spring clips
→ possibility of connecting power supply both “from above“ and “from below”
→ sealable in on and off position róalso without fuse-link inserted,
→ operating categories: AC 22B, AC 23B (35A), DC 22B,
→ Rated short-circuit capacity [kA]: 50,
→ 1-pole version, 2p, 3p, 1p+N, 3p+N,
→ rated current depending on inserts from 2 to 63A,
→ the use of a disconnector with a insert enables selective cooperation with overcurrent circuit breakers.
