Abstract

A motor protection relay including a housing and a printed circuit board disposed within the housing, the printed circuit board including a central processing unit and a wireless communication interface, the wireless communication interface adapted to receive wireless communication signals for configuring operating parameters of the motor protection relay via the central processing unit.

First claim

I claim:

1. A motor protection relay, comprising:
a housing; and
a printed circuit board disposed within the housing, the printed circuit board including a central processing unit and a wireless communication interface, the wireless communication interface adapted to receive wireless communication signals for configuring operating parameters of the motor protection relay via the central processing unit;
wherein the printed circuit board includes a first printed circuit board section, a second printed circuit board section and a third printed circuit board section electrically connected to one another by a flexible interconnect member, wherein the first printed circuit board section and the third printed circuit board section are oriented perpendicular to the second printed circuit board section.

2. The motor protection relay according to claim 1 , wherein the wireless communication interface enables wireless communication using at least one of Bluetooth, Wi-Fi, and ZigBee wireless communication protocols.

3. The motor protection relay according to claim 1 , wherein the operating parameters include at least one of voltage settings, current settings, inverse or instantaneous phase overcurrent protection settings, phase to phase protection settings, phase unbalance protection settings, ground fault protection settings, motor jam protection settings, underload or under power protection settings, off-nominal frequency protection settings, out of phase sequence condition settings, motor backspin settings, emergency motor override settings, and current transformer settings.

4. The motor protection relay according to claim 1 , wherein the printed circuit board is covered by a protective conformal coating.

5. The motor protection relay according to claim 4 , wherein the conformal coating is a polymeric film.

6. A motor protection relay comprising:
a housing; and
a printed circuit board disposed within the housing, the printed circuit board including a central processing unit and a wireless communication interface, the wireless communication interface adapted to receive wireless communication signals for configuring operating parameters of the motor protection relay via the central processing unit;
wherein the printed circuit board includes a first printed circuit board section, a second printed circuit board section and a third printed circuit board section electrically connected to one another by a flexible interconnect member, wherein the first printed circuit board section and the third printed circuit board section are oriented perpendicular to the second printed circuit board section; and
wherein the motor protection relay is devoid of a physical user interface located within, or on an exterior of, the housing.
