Electrical Relay ALLNET ALL3527B Blue White

The ALLNET ALL3527B Blue White is an electrical relay designed for reliable switching in control circuits. It accepts a 12 V AC input coil and switches AC loads up to 250 V at a rated current of 10 A. The component’s compact form and clear color marking support straightforward installation and identification in distribution panels, control boxes, or modular assemblies where space and clarity are important.

Advantages

This electrical relay provides stable operation with a 12 V AC coil and a high-voltage switching capability up to 250 V AC at 10 A, which makes it suitable for many general-purpose control tasks. The blue and white design helps with visual identification, while the mechanical construction is intended for consistent contact performance over repeated cycles. The relay’s ratings make it compatible with common household and light industrial AC loads, providing safe and predictable switching behavior when installed according to specifications.

Suitable for

• Switching lighting circuits and small motors within the 10 A rating
• Control circuits in HVAC and building automation systems
• Relay boards and modular control panels requiring 12 V AC coil operation
• Replacement part for compatible 12 V AC relay sockets

Key specifications

• Coil operating voltage: 12 V AC
• Maximum switched voltage: 250 V AC
• Rated switching current: 10 A
• Contact type: single-pole (typical for this class of relay)
• Color: blue and white housing

How to use

Mount the relay in a suitable socket or on a panel following the equipment manufacturer’s mechanical and electrical guidelines. Connect the 12 V AC coil to the designated input terminals and route the load through the relay’s switching contacts rated for up to 250 V AC and 10 A. Ensure wiring is secure and that terminal screws or connectors are tightened to the recommended torque. Verify correct coil polarity where applicable and confirm that the connected load does not exceed the relay’s current and voltage ratings before powering the circuit.

Recommendations

Use the relay within its specified voltage and current limits and in an environment free from excessive vibration, moisture, and dust. For long service life, avoid frequent switching at the maximum rated current and provide appropriate overload protection such as fuses or circuit breakers. When integrating into safety-related systems, follow applicable standards and perform regular inspection of contacts and terminations.
