GE TQL100F Mod.10 / TQL100S Mod.10 NEMA Type 1 Breaker Enclosure, 100A 240VAC, w/ Installed Breakers 15A + 30A

Condition: Used; light cosmetic wear from service/handling. Breakers are present (1×15A and  2x30A unit).

This is a GE circuit breaker enclosure designed to house compatible GE breakers for compact branch distribution or local disconnect/protection. Based on the nameplate, it’s a Type 1 (indoor, dry location) metal enclosure rated 100A, 240VAC max for the enclosure and neutral. It includes knockouts for conduit/cable entry and a neutral/ground terminal assembly. The pictured unit is populated with a 15A breaker (commonly used for a 120V branch) and a 30A breaker (often used as a 240V load breaker—verify poles by the breaker label/handle). These enclosures are commonly used for HVAC equipment feeds, small sub-feeds, and service/maintenance branch circuits where a rugged, code-recognizable breaker-in-a-can solution is preferred.

Features

• Steel indoor enclosure for breaker-based protection/disconnect
• Type 1 rating for electrical rooms, mechanical rooms, shops, and other dry interiors
• Knockouts for flexible routing of conduit/cable entries
• Neutral/ground terminal provision with published torque specs
• Designed for specific GE breaker families (helps ensure proper fit and listing compliance)
• Front cover provides guarded access with a breaker handle opening

Applications

• HVAC/R: local feed protection for condensers, air handlers, heat kits, pumps, control power branches (as allowed by code/inspection)
• Electrical distribution: small branch panels, equipment feeds, sub-circuits in commercial/industrial spaces
• Industrial/MRO: localized machine or auxiliary circuit protection
• Facilities/Building services: dedicated circuits for support equipment, maintenance outlets, controls

Cross-Referenced / Compatible Models (per enclosure marking)

Comparable Products

• Square D / Schneider breaker enclosures for QO or Homeline
• Siemens breaker enclosures for QP
• Eaton / Cutler-Hammer breaker enclosures for BR or CH
• Other NEMA 1 “breaker-in-a-can” indoor enclosures with similar ampacity class

System / Assembly Use (how it fits into larger installations)

• Commonly installed between a main panel and a dedicated load as a local branch protection point
• Typical patterns:
  • Main panel → 30A (often 2-pole) → 240V equipment (e.g., HVAC condenser, heater, pump—application dependent)
  • Optional additional 15A branch → service receptacle, controls, or auxiliary load
• For HVAC “near equipment disconnect” requirements, some jurisdictions require a lockable disconnect—this enclosure may or may not satisfy that requirement depending on configuration and inspection authority.
