What it does on the line
The 1SDA066989R1: This handheld unit connects to the Ekip trip unit's front test port to verify protection settings, download parameter sets, and read event logs without powering down the breaker. For a panel builder or commissioning engineer, it replaces the need to carry a laptop with Ekip Connect software into the switchgear — the T&P unit is a dedicated, rugged field tool.
The lifecycle stage is current, meaning ABB continues to manufacture and support the 1SDA066989R1. It is a qualified part on the BOM for any installation using Ekip trip units.
