DCM RBS / TBP / TACR — remote battery switch and battery protection relay up to 500 A
Country: Netherlands · Model: DCM-RBS / DCM-TBP / TACR-160
The DCM series switching devices are rated for a continuous current of 500 A in 12/24 V systems and 350 A at 48 V, with a rated voltage of 60 V DC. They are installed in DC battery systems to switch the battery off remotely, protect it from deep discharge and combine batteries during charging.

Description
The DCM-RBS works as a remote battery switch operated by a button or from a panel, so the power cable does not have to be run to the driver's or helmsman's position. The DCM-TBP disconnects the load when the battery approaches deep discharge and preserves its service life without human involvement. The TACR-160 is an automatic 160 A charging relay that connects the starter and service batteries while charging is under way and disconnects them when it is finished. The devices withstand an inrush current of 1000 A for 1 min, which covers the current surge when switching on an inverter with a large input capacitance. The 500 A rating applies to 12 and 24 V, and in a 48 V system the current margin is counted from 350 A.
How to choose
The task determines the type of device. For manual or remote battery disconnection you need the DCM-RBS, for automatic deep discharge protection the DCM-TBP, and for charging two batteries from one source the TACR-160. Then check that the load current does not exceed 500 A at 12/24 V or 350 A at 48 V and that the system voltage stays within 60 V DC. Fuse holders and busbars for assembling a unit with these devices are available in the DC Modular (DCM) system, including double-row busbars rated 300 A.

FAQ
How does the DCM-TBP differ from the DCM-RBS?
The DCM-RBS switches the battery off on the operator's command, while the DCM-TBP does it automatically when the battery approaches deep discharge. Both are rated for 500 A in 12/24 V systems.
What is the rated current of the DCM relays at 48 V?
At 48 V the rated current is 350 A, and for 12 and 24 V it is 500 A. The rated voltage of the devices is 60 V DC.
What is the TACR-160 relay used for?
It is an automatic 160 A charging relay that combines the batteries during charging and separates them afterwards. It is installed between the starter and service batteries of a motorhome or boat.
Will the DCM contacts withstand the inrush current?
The device briefly passes 1000 A for 1 min. The actual starting current of a starter or inverter must be checked against this value before installation.
