1. Product Name

Allen Bradley 1394-SR36A Miniature Contactor with Auxiliary Contacts for Precision Control

2. Product Introduction

The Allen Bradley 1394-SR36A is a specialized Allen Bradley Miniature Contactor, designed for precision motor control in wheat agricultural (small irrigation pumps, grain sorters) and light industrial scenarios, featuring built-in auxiliary contacts.

3. Product Description

The Allen Bradley 1394-SR36A is a high-precision Allen Bradley Miniature Contactor, part of Allen Bradley’s 1394 series focused on accurate motor control for low-to-medium duty applications. As a dedicated Allen Bradley Miniature Contactor, it supports 120V AC control voltage and 240V AC power circuits—ideal for matching the power demands of small to mid-sized wheat farm equipment (e.g., 2HP irrigation pumps, 1.5HP grain sorting machines) and light industrial tools, eliminating the need for extra voltage regulators.

Constructed with UL94 V-0 flame-retardant plastic housing and silver-nickel plated copper contacts, the Allen Bradley Miniature Contactor resists arcing from frequent on-off cycles, wheat field dust, and minor mechanical vibrations—critical for maintaining stability in farm sheds or compact industrial workshops. Its 20A rated current is perfectly suited for controlling 0.5–2HP motors, commonly used in wheat post-harvest processing tools like small grain cleaners and seed separators. A key highlight is its built-in 1NO (Normally Open) auxiliary contact, enabling signal feedback for equipment status monitoring (e.g., pump running indicators), which simplifies system integration. The compact design (approx. 85×52×38mm, 150g) supports 35mm DIN rail mounting, saving space in control cabinets and reducing installation time by 30%.

Compliant with IEC 60947-4-1, UL 508, and CSA C22.2 No. 14 standards, this Allen Bradley Miniature Contactor operates stably in -25°C to 60°C temperatures and handles up to 75% non-condensing humidity. It delivers 3 million mechanical operations and 400,000 electrical operations—sufficient for 4–5 wheat cultivation cycles or 3 years of industrial use—lowering maintenance frequency and replacement costs.
