ABB TSM420CSCUP 200A Meter Load Center – 4 Space Center Main Breaker

Description

Product Overview

The ABB TSM420CSCUP 200A Meter Load Center is engineered for demanding outdoor environments where reliability and safety are paramount. Constructed with a one‑piece copper bus that is tin‑plated for superior corrosion resistance, the unit provides a solid electrical pathway that minimizes voltage drop and extends service life. The enclosure meets NEMA 3R standards, featuring a galvanized steel shell that protects internal components from rain, dust, and extreme temperatures. With a compact footprint of 13.6″ L x 4.47″ W x 3.8″ H, the load center fits neatly into standard outdoor panels while delivering a high current capacity of 200 amps.

Designed for both overhead and underground meter installations, the TSM420CSCUP incorporates a ring‑type meter socket that accepts 1‑inch THQL and 1‑inch L‑type meters, providing flexibility for a range of utility configurations. The factory‑installed main breaker offers four 1‑inch breaker spaces, supporting up to eight circuits in total, which allows users to segment lighting, receptacles, HVAC, and specialty loads efficiently. The breaker is a thermal‑magnetic type that delivers precise trip characteristics, protecting downstream circuits from overloads and short circuits.

Usage

This load center is ideal for residential homes, small commercial buildings, and light industrial facilities that require a durable outdoor power distribution solution. Installers can mount the unit on exterior walls, utility poles, or dedicated meter bases, taking advantage of its weather‑resistant design to safeguard against moisture ingress and UV exposure. The generous wire space within each breaker slot accommodates #6 AWG copper conductors, simplifying the termination process and reducing the need for additional splicing. Whether upgrading an existing service entrance or constructing a new build, the TSM420CSCUP provides a straightforward path to meet code‑mandated grounding and bonding requirements.

Because the load center includes a hinged, removable door, routine inspections and maintenance tasks can be performed without removing the entire panel. The door opens to reveal a clear layout of breaker positions, making it easy for electricians to identify circuits, replace breakers, or add new loads. The integrated feed‑through lugs allow for direct connection to the service entrance cable, eliminating the need for separate jumper conductors and reducing installation time.

Why Choose Us

ABB brings decades of expertise in electrical distribution, and the acquisition of GE Industrial Solutions has expanded its portfolio with proven, high‑quality products. The TSM420CSCUP reflects this heritage through rigorous testing, adherence to UL standards, and a commitment to long‑term reliability. Customers benefit from a comprehensive warranty that covers manufacturing defects, providing peace of mind and protecting the investment in critical infrastructure.

Beyond the robust construction, the load center offers practical advantages that streamline project workflows. The pre‑wired main breaker eliminates the need for separate breaker procurement, while the integrated meter socket reduces part count and simplifies inventory management. ABB’s global support network ensures that technical assistance, replacement parts, and documentation are readily available, minimizing downtime in the event of service interruptions.

Environmental sustainability is also a core consideration. The tin‑plated copper bus reduces the risk of corrosion, extending the product’s usable life and decreasing the frequency of replacements. The recyclable steel enclosure aligns with industry efforts to reduce waste and promote responsible material usage.

FAQ

What size breaker can be installed in the TSM420CSCUP?

The load center includes a factory‑installed 200 A main breaker and four additional 1‑inch breaker slots that can accommodate standard thermal‑magnetic breakers up to 30 A each, allowing for flexible circuit distribution.

Is the enclosure suitable for direct burial?

While the NEMA 3R rating offers excellent protection against weather, the enclosure is not rated for direct burial. It should be mounted on a surface that provides adequate clearance from the ground.

Can this load center be used with both overhead and underground meters?

Yes, the ring‑type meter socket is compatible with 1‑inch THQL and 1‑inch L‑type meters, making it suitable for a variety of utility configurations, whether overhead or underground.

What is the warranty coverage for this product?

ABB provides a standard manufacturer’s warranty that covers defects in materials and workmanship for a period specified in the product documentation, typically one year from the date of purchase.

How does the hinged door improve maintenance?

The hinged, removable door gives technicians quick access to the breaker layout and wiring, reducing the time required for inspections, troubleshooting, and component replacement.
