DC Power Contactors

DC Switching Contactors – High‑Duty Direct‑Current Control for EU Infrastructure

DC contactors are essential when switching direct current loads—typical in renewable energy, battery systems, EV chargers, and DC motor drives. Unlike AC contactors, DC units must manage arcing reliably, making them more rugged and highly engineered. At Bank of Lamps, we supply a curated range of dc contactor models from ABB and Eaton, all supported by EU certifications and B2B logistics.

Key Models of Contactor DC Available

We stock top-tier dc contactors suited to varied amperage and coil-voltage needs:

• ABB GAE75‑10‑11 (50 V DC) – up to 22 kW AC/4 kW DC rating; built-in magnet arc chutes; 1 auxiliary contact
   
• ABB TAE75‑30‑00 (42‑78 V DC) – 3-pole switch rated for up to 690 V AC / 220 V DC; optional side and front auxiliary contacts
   
• Eaton DILEM‑01‑G (220 V DC) – compact 3-pole contactor with 1 NC auxiliary contact; 12 A at AC‑3; ideal for control circuits
   

Each contactor with auxiliary contacts supports secure switching logic integration, while main contacts handle high-power DC switching (up to several hundred amps depending on series).

DC Contactor Applications – Where They Fit

These dc contactors deliver reliable performance in:

• Photovoltaic string-level disconnect and inverter switching
   
• EV chargers and battery backup cabinets
   
• DC bus switching in renewable energy and telecom systems
   
• Industrial DC motor isolations and braking controls
   
• Rail, lift, and crane installations with DC control requirements
   

All are DIN-rail or panel mountable, suitable for compact distribution or automation control enclosures.
