Bi-directional battery contactor for thermal currents up to 60 amps.
C110B –bi-directional battery contactor
The Schaltbau C110B series stands for configurable 1 pole, bi-directional DC battery contactors up to 48 volts (80 volts rated insulation voltage) and continuous currents up to 400 amps.
C110B/80
C110B/120
Bi-directional battery contactor for thermal currents up to 100 amps.
C110B/200
Bi-directional battery contactor for thermal currents up to 150 amps.
C110B/300
Bi-directional battery contactor for thermal currents up to 250 amps.
C110B/400
Bi-directional battery contactor for thermal currents up to 400 amps.
With the bi-directional C110B DC contactor, Schaltbau offers an economic solution for the switching of battery voltages of up to 48 volts (80 volts rated insulation voltage). The single-pole NO contactor is available in four sizes: for conventional thermal currents up to 60, 100, 150, 250 and 400 amps.
The C110B meets the standard for battery power-operated industrial trucks (EN1175). As a main contactor in industrial trucks, it connects battery and drive and, if required, it can disconnect the connection securely: both in normal operation (battery discharge) and during the charging process. Since this DC contactor can switch bi-directionally, it is also recommended for numerous other stationary and mobile battery applications with an operating voltage of up to 48 volts; e.g. for battery chargers, mobile lifting platforms and automated guided vehicles (AGVs) in intralogistics.
Features
Bi-directional DC contactor in five standard sizes
The C110B is available in four sizes, for carrying 60, 100, 150, 250 or 400 amps. The connecting dimensions correspond with the usual market standard.
Enclosed contact area
Thanks to the enclosed design, no dirt or dust can ingress into the contact area. The contacts are preserved.
Optimised for the requirements of industrial trucks
The C110B DC contactor has been tested according to EN1175: the standard for battery power-operated industrial trucks. In industrial trucks it can work both as a main contactor and also switch subsystems, such as pumps.
Additional applications for bi-directional switching
The C110B is proven in numerous stationary and mobile DC applications in which switching must be bi-directional:
- Battery chargers (battery booster)
- Battery switchgear
- Corridor cleaning machines
- Mobile electric lifting platforms
- Automated Guided Vehicles (AGVs) for intralogistics
The contactor complies with the standards EN1175, IEC 60947-1 and IEC 60947-4-1.
