D23MR08A CUTLER-HAMMER Relay

Review CUTLER-HAMMER 300v Type Relay Unused

The Cutler-Hammer D23MR08A is a versatile 300V AC coil relay with a formidable capacity to handle heavy-duty applications. This particular model is part of the D23 series, which is renowned for its reliability and durability.

The D23MR08A is a normally open (NO) relay, meaning it does not conduct current until it is energized by an external source. It features eight contacts, including four normally open (NO) contacts and four normally closed (NC) contacts. This extensive contact arrangement allows for a variety of wiring configurations, making it suitable for a wide range of industrial and electrical control systems.

The relay is rated for a maximum operating voltage of 300V AC. It can handle a current of up to 10 Amperes at 300V AC, ensuring it can handle heavy loads. The contacts are rated for a contact capacity of 1000 amps at 300V DC for a short period of time and 50 amps at 300V AC for a long period of time.

This Cutler-Hammer relay is built with premium materials to ensure its longevity and performance in demanding environments. It has a silver-plated contact material that provides excellent conductivity and resists corrosion, ensuring consistent and reliable contact performance over time. The contacts are also gold-plated for added durability and to minimize contact resistance.

The D23MR08A is designed with a latching mechanism, meaning it will stay in its last position until it is re-energized. This feature can be useful in applications where it's important to maintain a specific state until a certain condition is met.

The relay is compact and measures 5.3 x 3.6 x 1.5 inches, making it a space-saving option for control panels and other electrical systems. It operates at a temperature range of -40 F to 140 F (-40 C to 60 C), ensuring it can function optimally in a wide range of environmental conditions.

The Cutler-Hammer D23MR08A is an essential component for industrial control systems, offering high performance, durability, and versatility. Its extensive contact arrangement and robust build make it a reliable choice for handling heavy loads and complex wiring configurations.
