T-470A Phase Sequence Indicator

TEGAM’s Phase Sequence Indicators show installers and service people the correct way to make three-phase connections and prevent costly damage. 

Working where power is on, TEGAM’s Phase Sequence Indicators instantly and clearly identify A/B/C circuits. 

There’s no more guesswork, no more damage to motors, machinery, switchgear or accessories. 

TEGAM indicators have both an ABC lamp and a BAC lamp. 

Just connect the Black/Red/Blue test leads to the three phase circuit. 

When correctly connected, the ABC lamp glows. 

A reversed sequence lights the BAC lamp. 

An open phase lights both lamps at 200 volts. 

It’s that easy, that fast.
