Description

The ABB 1SCA115402R1001 (Internal Designation: OZXB4) is a heavy-duty, touch-safe terminal shroud kit designed for industrial low-voltage switch-disconnectors and change-over switches. It provides localized IP20 electrical shock protection by shielding exposed line or load terminals against accidental finger or tool contact.

Technical Specifications

Field Experience & Engineering Insights

Application and Mechanical Fitment

In field deployments, the OZXB4 terminal shroud kit is a critical accessory for meeting finger-safe requirements inside industrial control panels, motor control centers (MCCs), and service entrance equipment. The clear or smoke-tinted polycarbonate configuration allows maintenance technicians to visually inspect terminal lugs for thermal discoloration, torque seal degradation, or corrosion without physically removing the protective barrier.

Installation Constraints

• Switchgear Compatibility: The OZXB4 is engineered exclusively for specific frame sizes within the ABB OS200, OS250, OT200, and OT250 switch-disconnector families. Do not attempt to force fit these shrouds onto smaller OT160 or larger OT400 frames, as the spacing distances between physical poles and terminal lugs vary.
• Snap-Lock Mechanisms: The shrouds use integral plastic snap-tabs that slide directly onto the molded channels of the switch body. Warning: In unheated, low-temperature environments below 0 °C, the polycarbonate compound becomes brittle. Apply steady, uniform pressure during installation to prevent snapping the retention tabs.
• Lug Interference: If utilizing oversized mechanical compression lugs or double-barrel terminal connectors, verify outer clearance boundaries against the internal dimensions of the shroud before mounting the assembly. Excessive bulk will prevent the shroud from snapping completely into its locked position.

System Integration & Compatibility Checklist

• Primary Disconnect Families: Compatible with ABB OT200, OT250, OS200, and OS250 series 3-pole switches.
• Regulatory Standards: Conforms to IEC 60947-1 finger safety guidelines and CE directives. Meets UL electrical enclosure safety requirements when properly fitted to UL-listed switch bodies.
• Environmental Compatibility: Designed to withstand continuous operating temperatures up to the maximum thermal thresholds of industrial switchgear housings.

Frequently Asked Questions

Can this 3-pole kit be used on a 4-pole switch assembly?

No. The OZXB4 contains exactly 3 individual shroud pieces intended for standard 3-phase line or load applications. For 4-pole switches (which include an additional neutral or auxiliary pole), you must procure a dedicated 4-pole kit (such as the OZXB5 variant) or purchase additional components to protect the final phase path.

Does the OZXB4 install on both the incoming line side and outgoing load side simultaneously?

A single OZXB4 kit contains 3 shrouds, which covers one side of a 3-pole switch (either top line inputs OR bottom load outputs). If your engineering design specifications mandate full IP20 insulation on both the line and load terminals concurrently, you must order two separate 1SCA115402R1001 kits per switch unit.

Can I remove these shrouds while the main distribution bus is energized?

No. While the shroud is non-conductive, tool slippage or hand contact with adjacent exposed conductors during removal poses a severe arc flash and electrocution hazard. De-energize and lock out the upstream circuit breaker or isolation mechanism before performing any maintenance or adjustments around the switch terminals.
