Latching Relays 100-250 Ampere 721

Product catalog summary

Overview: The document provides technical specifications and details for the Gruner AG Type 721 Polarized Latching Relay, designed for high shock and vibration resistance, suitable for applications requiring up to 100 A.

Specifications:

Coil Data: Rated voltage ranges from 6 to 48 VDC, with a rated power of 4.5 W and operating power of 3.0 W. The pulse to set is 20 ms with an action time of less than 15 ms.
Contact Data: Maximum switching power is 25,000 VA, with a maximum switching voltage of 440 VAC and a maximum switching current of 100 A. The relay has a mechanical life of 10⁶ operations.
Insulation: Creepage and clearance distance is 8 mm, with a test voltage of 4,000 V between coil and contact, and 2,000 V between contacts. The dielectric strength is 12 kV/1.2/50μs.
General Data: The relay operates in ambient temperatures from -25 to +70 °C and weighs 75 g. It conforms to VDE, UL, CSA, SEV, and SEMKO standards.

Design and Features:

The relay uses the H-armature principle for high resistance to shocks and vibrations, ensuring no loss of information during power failures.
Manual operation is possible, and the relay is dust-protected to prevent flux and solder vapors from entering.
Power terminals can be customized according to customer specifications.

Shunt Integration:

Type 721 CR/DR includes a shunt for energy measurement and load shedding in energy management systems. The shunt data varies with temperature, affecting resistance values.

Dimensions: Detailed dimensions are provided for installation, with options for customer-specific modifications.
