The 32V 250A Heavy-Duty Latching Time Delay Relay disconnects the battery from the vehicle electrical system with voltage self-recognition. It is rated for 12V/24V with a voltage range of 8.5V to 32V.
Thanks to its IP67/X9K dust-tight, waterproof rating, non-volatile memory, low-battery alert system, and thermal protection, this heavy-duty latching time delay relay is ideal for heavy-duty trucks, buses, construction and agricultural equipment, and military applications.
The bi-stable remote battery disconnect relay also features immediate switch ON, controlled switch OFF, a programmable delay time from 1 second to 1 hour, and service state managing (service switch OFF and switch ON).
- Continuous current rating of 250 A, maximum short circuit rating of 2 kA at 5 s, and maximum cranking current of 800 A at 30 s
- Rated for 12V/24V with a maximum rating of 32V
- Programmable time delay from 1 second to 1 hour
- Built-in TE Superseal connector 1.5 series
- Remote command line for normal working (switch) and remote command line for SERVICE/EMERGENCY working (push button)
- NORMAL/SERVICE mode selection with power down restore
- Immunity to dirty switches
- Lamp driving line for error/status signaling
- UNECE R10 Rev05 compliant
