American Zettler 12VDC Power Relay AZ2280-1A-12DF SPST-NO 155Ω 30A

Description

Product Overview

The American Zettler AZ2280-1A-12DF is a 12VDC power relay engineered for high‑current applications such as furnaces, HVAC units, and other industrial control systems. With a rated current of 30 A and a coil resistance of 155 Ω, this relay offers reliable actuation and consistent performance even under continuous load. Its SPST‑NO (single pole, single throw, normally open) contact configuration simplifies wiring while providing a clean, low‑resistance path when energized. The compact dimensions of 6 × 4 × 6 inches allow easy integration into tight panels, and the lightweight design (0.01 oz) reduces overall system weight. Constructed from durable metal housing and high‑quality contact materials, the relay meets rigorous standards for longevity and safety.

Usage

This relay is ideally suited for residential and commercial furnace replacement projects, HVAC control boards, and any application requiring precise 12 VDC switching. Installers can use it to control blower motors, heating elements, and safety interlocks, ensuring that equipment starts and stops exactly when needed. The 30 A rating accommodates most standard furnace blower motors, while the 155 Ω coil provides a stable draw that is compatible with typical control transformers. Because the relay is not discontinued by the manufacturer, it remains a reliable choice for maintenance and retrofit scenarios. Its straightforward wiring—one coil connection and a single set of contacts—makes it accessible to both seasoned technicians and DIY enthusiasts.
