The Schneider Electric VCDN20 is a TeSys Mini-Vario emergency stop switch disconnector designed for industrial applications requiring reliable and safe operation. This device features a 3-pole configuration with 3 normally open contacts, suitable for both AC and DC networks. It is equipped with a rotary handle control, mounted directly on the door, with a red handle and a yellow front plate, allowing for padlocking with 1 to 3 padlocks (4 to 8 mm) to prevent unauthorized operation. The VCDN20 has a conventional free air thermal current (Ith) of 20 A and a conventional enclosed thermal current (Ithe) of 16 A. Its rated operational current (Ie) is 11 A at 400 V in AC-23 duty. The device offers a rated operational power of 4 kW at 230-240 V, 5.5 kW at 400-415 V, 7.5 kW at 500 V, and 11 kW at 690 V, all in AC-23 duty. In AC-3 duty, it provides 3 kW at 230-240 V, 4 kW at 400-415 V, 5.5 kW at 500 V, and 5.5 kW at 690 V. The VCDN20 is designed for mechanical durability of 50,000 cycles and electrical durability of 30,000 cycles in DC-1 to DC-5 applications, and 50,000 cycles in AC-21 applications. It is suitable for isolation and features screw clamp terminals for power circuit connections, accommodating cables up to 4 mm² in cross-section. The device has an IP65 rating, ensuring protection against dust and water ingress, making it suitable for harsh industrial environments. The VCDN20 complies with international standards, including IEC 60947-3, and is certified by UL, GL, CCC, and CSA, ensuring its reliability and safety in various industrial settings.
