This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

Higher Capabilities for Safety-Rated Control Circuits A truly reliable safety control system must work even when some parts fail. Force-guided relays are unseen components that add another level of ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

Relays, Contactors, and Motor Starters provides an overview of the primary components involved in electric motor control. Relays are electrical switches that control a circuit. When activated by ...

GTM400 and GTM500 contactors can handle applications up to 1500V and are the first products released as a part of Sensata’s new GTM contactor family. The products will be showcased for the first time ...

What is a pre-charge circuit and what role does it play? The fundamental elements of a pre-charge circuit. Some basic best practices and where to find more information. A common challenge in systems ...

Safety is a major concern in a good many motor-driven applications. This is true in industrial applications where motion starts when power is applied and especially true when power is restored after ...

The Contactron solid-state reversing contactor from Phoenix Contact combines four functions in a module that’s just 22.5 mm wide (see the figure). Designed for three-phase ac motors up to 4 kW/5 HP in ...

Figure 1. Restructuring the circuit in Figure 2 with redundant machinery power contactors and a double-pole interlock switch increases the probability that the circuit will work, even if a single ...
