FURNAS ELECTRIC CO Contact Block 3SU1400-1AA10-1BA0 Front Mount 1NO

Description

Product Overview

The FURNAS ELECTRIC CO 3SU1400-1AA10-1BA0 Contact Block is a precision‑engineered terminal designed for front‑mounting in a wide range of industrial control environments. Constructed from high‑grade copper alloy with a protective polymer housing, the block delivers excellent conductivity while resisting corrosion, vibration, and temperature extremes common in manufacturing facilities. Its compact footprint—measuring just 1.18 x 1.18 x 0.39 inches—allows it to fit into dense panel layouts without sacrificing performance.

Each contact within the block is engineered to provide a secure 1NO (single‑pole normally open) connection, ensuring reliable signal transmission and power distribution. The block’s snap‑in design eliminates the need for additional fastening hardware, reducing installation time and minimizing the risk of loose connections. With a rated current capacity suitable for most low‑voltage applications, this terminal block meets IEC standards for safety and durability.

Key specifications include a weight of only 0.35 ounces, a robust UL rating, and compatibility with standard wire gauges ranging from 22 to 12 AWG. The product is not discontinued by the manufacturer, guaranteeing ongoing support and availability for long‑term projects. Its ASIN B00YWMK7BY and strong sales rank (#59 in IO Blocks) reflect its popularity among engineers seeking dependable, space‑saving solutions.

Usage

This contact block excels in environments where space is at a premium and reliability cannot be compromised. Typical applications include automation panels, PLC cabinets, motor control centers, and distributed control systems. The front‑mounting capability allows technicians to access the terminals from the panel front, simplifying troubleshooting and reducing downtime during maintenance.

Because of its durable construction, the block performs well in harsh conditions such as chemical processing plants, food‑processing facilities, and outdoor enclosures with appropriate sealing. It is also suitable for prototype builds and small‑batch production lines where quick reconfiguration is required. The intuitive snap‑in mechanism makes it an excellent choice for both seasoned electricians and newcomers to industrial wiring.

When integrating the block into a system, ensure that the wire is stripped to the recommended length and that the terminal is fully seated before applying torque. This practice maximizes contact integrity and extends the service life of the component.
