Description

Why Upgrade to the Next-Generation TESCO 4E2-1?

Enhanced Safety and Crew Awareness

Dual-mode indication with high-visibility LEDs and an integrated audible alarm provides immediate voltage-present confirmation for both the operator and surrounding crew members.

Extended Operator Clearance

A four-foot reach increases the distance between personnel and energized third rail surfaces, supporting safer field verification procedures.

Ingress-Protected Design

Fully enclosed internal circuitry eliminates exposed lamp windows and helps reduce moisture and debris intrusion concerns in demanding transit environments.

Redundant Circuitry and Overvoltage Protection

Engineered with multiple safety paths and overvoltage protection to minimize failure points and support operational reliability.

Complete Third Rail Voltage Verification Safety Solution

Safe third rail verification involves more than detecting voltage presence alone. The Next-Generation TESCO Third Rail Voltage Detector (4E2-1) and the Third Rail Voltage Detector Self-Test (4E2-1ST) work together to support a more complete field safety and verification process.

Designed as a “tester for the tester,” the TESCO Third Rail Voltage Detector Self-Test (4E2-1ST) provides crews with a fast and reliable method to confirm detector functionality before entering the field. This added verification step helps support operational readiness and crew confidence, particularly in territories where active third-rail power may not be available for live confirmation.

Lightweight and portable, the self-test unit fits directly inside the TESCO 4E2-1 carrying case, making it easy for crews to transport and store alongside the detector.
