RC circuit for surge suppression Suitable for 24-48V AC Protects 3RT2.1 and 3RH2 contactors Dampens inductive kickback Enhances component life

Product description

The Siemens 3RT2916-1CB00 is an RC element surge suppressor designed to protect contactors from voltage transients. It operates with AC voltages of 24-48V (50/60 Hz) and DC voltages of 24-70V. This suppressor is specifically engineered for use with Siemens 3RT2.1 and 3RH2 auxiliary contactors to provide reliable suppression of inductive voltage spikes.

RC surge suppressors are often preferred for their effectiveness in dampening switching transients in inductive circuits. This component is vital in automation systems, motor control, and power switching applications where reliable contactor operation is essential, such as in factory automation, machine tools, and HVAC systems.

Stanlo Automation, a veteran-owned distributor of surplus industrial automation parts, offers the Siemens 3RT2916-1CB00. We provide quality components and reliable service, ensuring you can source the parts needed to keep your automated systems running efficiently.

Frequently asked questions

What type of surge suppression technology does the Siemens 3RT2916-1CB00 use?

The Siemens 3RT2916-1CB00 utilizes an RC (Resistor-Capacitor) element for surge suppression. This technology is effective at absorbing and dissipating transient energy, particularly from inductive loads, protecting the associated contactors.
