[Mitsubishi Electric] - SHD-V400 Vacuum Magnetic Contactor (DC operated, 450A Ith, 400A 200kW at AC440V)

Mitsubishi Electric MS-T/N series SHD-V400 large capacity vacuum magnetic contactor combining a vacuum switch with an AC operated DC excited electromagnet for high performance, long life and maintenance free operation. Rated insulation voltage 1500V three phase, rated operational current and capacity 400A 95kW at AC220V, 400A 200kW at AC440V, 400A 250kW at AC550V, 400A 500kW at AC1000V, 400A 750kW at AC1500V, three phase capacitor rating 300A 100kVA at AC220V, 300A 200kVA at AC440V, 300A 250kVA at AC550V, open thermal current 450A. No arc clearance is required so the panel can be made smaller, there is no coil humming or current interruption noise, and there is no arc blowout which keeps the unit safe in harsh ambient conditions. Switching frequency 1200 operations per hour. Electrical 500,000 operations on three phase motor AC-3 class, 100,000 operations on three phase capacitor, mechanical 2,500,000 operations. Standard auxiliary contacts 2a2b, with a 4a4b configuration available on request. Compliant with JIS C8201-4-1, JEM 1038, IEC 60947-4-1. A surge absorber is not required for motor loads of 7.5kW and above but should be fitted for loads of 5.5kW and below. SH-V160 to V600 carry UL component recognition and CSA certification.
