Relé de instalación ABB con bobina 24 V AC/DC, 16 A, 1 NA + 1 NC, carril DIN, E297-16-11/24 2TAZ311000R2043

Electricians and panel builders install the ABB E297-16-11/24 installation relay in distribution boards and control cabinets to switch lighting, heating, or motor loads up to 16 A. The relay coil accepts 24 V AC or DC, making it compatible with common building automation control signals. It provides one normally open and one normally closed contact, so it can be used for both switching and interlocking functions. The compact module width of 18 mm saves space on the DIN rail, while screw terminals ensure secure wiring.

Key specifications

• Coil supply voltage: 24 V AC/DC
• Rated operational current: 16 A
• Contact configuration: 1 NO + 1 NC
• Rated operational voltage: 250 V AC
• Mounting: DIN rail
• Module width: 18 mm
• Terminal type: screw terminals
• Operating temperature range: -25 to +55 °C
• Electrical durability: 150,000 cycles
• Mechanical durability: 1,000,000 cycles

Why choose it

The relay handles both AC and DC coil supply, simplifying inventory for mixed control systems. Its 16 A rating covers many lighting and small motor circuits, and the two contacts offer flexibility for control logic. DIN rail mounting speeds up installation in standard enclosures.

Ideal use cases

• Switching lighting circuits in residential and commercial buildings
• Controlling small motors or pumps in HVAC systems
• Interlocking safety circuits in industrial control panels
• Building automation systems with 24 V control signals

Good to know

The relay is designed for use in dry indoor environments. It complies with relevant IEC standards for installation relays. Screw terminals accept a range of conductor sizes, and the IP20 terminal protection requires installation inside an enclosure.
