Why Choose the ABB E290-32-20/8 Latching Relay?
The ABB E290-32-20/8 is a high-current electromechanical latching relay designed for impulse-controlled switching in lighting, building control and electrical distribution applications. Part of the ABB E290 range, it combines a 32 A rated current with two normally open contacts, providing simultaneous switching of two circuits from a compact DIN rail device.
The E290-32-20/8 uses an impulse-operated mechanical latching mechanism. A short electrical control pulse changes the relay state, after which the contacts remain mechanically held in their selected position without continuous coil energisation until another switching impulse is applied.
With a 250 V AC rated operating voltage and 8 V AC control voltage, this model combines high-current load switching with low-voltage impulse control. Its 2NO contact arrangement is particularly useful where two normally open switching paths need to operate together from the same control command.
Key Advantages
- High 32 A rated current for demanding electrical switching applications.
- Two normally open (2NO) contacts for simultaneous switching functions.
- 8 V AC control voltage for compatible low-voltage impulse-control circuits.
- Mechanical latching retains the switching state without continuous coil energisation.
- Front operating lever provides manual operation and contact-position indication.
- Compact 18 mm DIN rail format for space-efficient panel installation.
Key Features
- ABB E290 electromechanical latching relay.
- 32 A rated current.
- 250 V AC rated operating voltage.
- 2NO normally open contact configuration.
- 8 V AC control voltage.
- Impulse-operated mechanical latching mechanism.
- Maintains its contact state without permanent coil power.
- Front manual operating facility and contact-position indication.
- DIN rail mounting with screw-terminal connections.
High-Current Dual-Circuit Impulse Switching
ABB E290 latching relays use short electrical control impulses to change their switching state. Once actuated, the internal mechanical mechanism holds the contacts in position without requiring continuous coil energisation. A subsequent control impulse changes the relay state again, providing an energy-efficient method of controlling loads from one or multiple switching points.
The E290-32-20/8 combines this operating principle with a 32 A switching rating, two normally open contacts and an 8 V AC control coil. This makes it suitable for applications where a low-voltage impulse circuit needs to operate two switching paths simultaneously while retaining the selected state mechanically.
Typical Applications
- High-current lighting control circuits.
- Lighting controlled from multiple push-button locations.
- Simultaneous switching of two electrical circuits.
- Residential and commercial building installations.
- Public buildings and communal lighting systems.
- Low-voltage impulse-control circuits.
- Industrial electrical installations.
- Electrical distribution boards and control panels.
