Q1L2100 - 100 Amp Circuit Breaker

Q1L2100 - 100 Amp Circuit Breaker

When you're replacing a breaker in an existing system, the details matter. The Q1L2100 is a 100-amp, 2-pole feed-through thermal-magnetic circuit breaker designed for equipment that uses the Q1L configuration. It's rated 120/240 VAC with a 10 kA I.C. rating and requires four spaces. The breaker measures 6.38 inches high, 1.5 inches wide, and 2.31 inches deep, giving you several important dimensions to compare against the breaker already installed. Its thermal magnetic design provides overload and short-circuit protection within the specified ratings. For maintenance work on compatible legacy equipment, the Q1L2100 can be a straightforward form, fit, and function replacement when the original part number and specifications match. It's built to last and, more importantly, built for the application it was designed to serve. Before installation, compare the part number, ratings, dimensions, and configuration with the existing breaker and equipment requirements.

Key Features and Benefits

• 100-amp, 2-pole design for equipment requiring this specific Q1L configuration.
• Feed-through construction is suitable for applications designed to accept this breaker style.
• Thermal-magnetic operation provides overload and short-circuit protection.
• Rated 120/240VAC with a 10k A.I.C. rating.
• The four-space requirement is another useful point to check when confirming fit.
• Clearly defined dimensions make it easier to compare the Q1L2100 with an existing breaker.
• Well-suited for form, fit, and function replacement in compatible legacy electrical equipment.
• Built to last when properly installed and used within its intended ratings.

Material Compliance and Certifications

• Material compliance details and specific agency certifications were not provided in the available specifications for the Q1L2100. These details shouldn't be assumed. If a particular listing, certification, or material requirement is necessary for your application, check the markings on the breaker and the appropriate technical documentation before installation.
  As with any circuit breaker replacement, the device should be installed only in equipment for which its electrical ratings, physical configuration, and breaker type are appropriate.

Where It Works Best

• The Q1L2100 makes the most sense when you're maintaining existing or legacy electrical equipment that was designed for a Q1L-type feed-thru breaker. This is about getting the right match—not changing the system simply for its own sake.
  If the equipment calls for a 100-amp, 2-pole breaker rated 120/240 VAC with a 10 kA I.C. rating, the Q1L2100 may provide the required form, fit, and function. Still, check the whole picture before installation. Part number, breaker type, dimensions, number of poles, amperage, voltage, interrupting rating, feed-through configuration, and the four-space requirement should all agree with the equipment specifications.
