Question 1

Where can I buy Siemens RL breaker parts?

Accepted Answer

Voyten Electric & Electronics, Inc. is the Siemens New Surplus source for Siemens Type RL breaker inventory worldwide. Voyten purchased all remaining RL and LA breaker inventory directly from the Siemens Wendell, NC manufacturing facility. New-surplus breakers, Static Trip III units, and every renewal part are tested, in stock, and ready to ship. Call 1-800-458-4001 or request a quote at voytenmanuals.com/contact.

Question 2

What is a Siemens Type RL breaker?

Accepted Answer

The Siemens Type RL is a low voltage power circuit breaker (LVPCB) in drawout construction, rated from 800A to 5000A. It uses the Static Trip III electronic trip unit for LSIG (Long-time, Short-time, Instantaneous, Ground fault) overcurrent protection. Variants include the RL (standard), RLE (economical — 800/2000/4000A frames), RLI (integrally fused — 800A), and RLF (fully rated). The RL product line also includes the companion Type LA air circuit breaker.

Question 3

What is the Static Trip III trip unit?

Accepted Answer

The Siemens Static Trip III is an electronic trip unit providing adjustable LSIG overcurrent protection for all RL series breakers. L = Long-time delay (adjustable pickup and time band), S = Short-time delay (I²t or flat response), I = Instantaneous (fixed or adjustable pickup), G = Ground fault (adjustable pickup and delay). Voyten stocks new-surplus and reconditioned Static Trip III units with full testing and calibration.

Question 4

What RL breaker frame sizes does Voyten stock?

Accepted Answer

Voyten stocks RL breakers and parts for all frame sizes: 800A, 1200A, 1600A, 2000A, 2500A, 3000A, 3200A, 4000A, and 5000A. The inventory includes 23 accessory categories covering every component from anti-pump relays and arc chutes to motor operators and undervoltage trip devices.

Question 5

Are Siemens RL breakers still manufactured?

Accepted Answer

No. Siemens discontinued the RL product line and closed the Wendell, NC facility. Voyten Electric purchased all remaining inventory, making them the Siemens New Surplus source for  RL breakers, LA breakers, Static Trip III units, and all renewal parts. Free technical documentation including instruction manuals (SGIM-3068), renewal parts catalogs (SG-3068), and wiring diagrams (SGIM-3068D) is available at voytenmanuals.com/products/rl-breakers.

Question 6

My Siemens RL breaker failed — who do I call for an emergency replacement?

Accepted Answer

Call Voyten Electric at 1-800-458-4001 for 24/7 emergency support. As the Siemens New Surplus source for Siemens Type RL inventory, Voyten identifies your breaker from its catalog or edge number, pulls an exact-match new-surplus or reconditioned RL/RLE/RLI/RLF breaker, Static Trip III unit, or renewal part from stock, tests it, and expedites shipment to minimize downtime in plants and critical facilities.

Question 7

How do I extend the life of aging RL switchgear instead of replacing it?

Accepted Answer

Because Voyten holds the complete Siemens RL inventory, aging RL switchgear can stay in service with genuine new-surplus and reconditioned RL breakers, Static Trip III trip units, and renewal parts — no need to replace the switchgear lineup. Voyten supplies exact-match components across all frames (800–5000A) so existing cells, bus, and wiring stay intact. Call 1-800-458-4001.

Question 8

How do I identify my Siemens RL breaker to order a replacement?

Accepted Answer

Provide the catalog number or the edge number stamped on the breaker frame, plus the frame size (800–5000A) and trip-unit model. Voyten cross-references these to the exact replacement breaker and parts. Call 1-800-458-4001 or request a quote at voytenmanuals.com/contact.
