ZALVB4 Description

Short technical summary and product information.

The Schneider Electric ZALVB4 is a light block designed for use with XB5 Ø 22 mm control and signalling units within the Harmony XAL range. This component features an integrated and protected red LED, providing steady illumination.

 

It is designed for rear mounting and utilizes screw clamp terminals for connections, compatible with cable sizes up to 2 x 1.5 mm² with cable end. The rated supply voltage is 24V AC/DC, with operating voltage limits specified from 19.2 to 30V DC and 21.6 to 26.4V AC. The current consumption is 18 mA, and the LED has a service life of 100,000 hours at rated voltage and 25 °C.

 

Environmental specifications include an operating temperature range of -40 to 70 °C and an IP20 degree of protection. The light block has undergone various resistance tests, including vibration (5 gn), shock (30 gn and 50 gn), fast transients (2 kV), electromagnetic fields (9.14 V/m), and electrostatic discharge (6 kV contact, 8 kV air). It also meets Class B electromagnetic emission standards.

 

This light block is suitable for customer assembly and is sold in indivisible quantities of 5. Its compact dimensions and rear mounting capability make it suitable for integration into various enclosures.
